Our platform unifies semantic observability, dynamic policy enforcement, and distributed monitoring to ensure agent ecosystems remain trustworthy, compliant, and efficient at scale.\nAs part of this mission, we are building an Intelligence Platform that is responsible for understanding, scoring, and optimizing agent behavior across the enterprise. Including accuracy, security, cost, drift, anomalous behavior, and runtime dynamics.\nRole Overview\nWe are looking for a Senior Applied AI Engineer to join our on-site Research & Intelligence team in San Francisco. This role is for an experienced engineer who enjoys working close to research problems but is primarily motivated by building, shipping, and improving production systems.\nYou will work on applied GenAI problems including agent evaluation, observability, and safety; translating proven techniques into scalable, reliable components within Alterion’s platform.\nThis is not a pure research role. Success is measured by what ships and what improves in production, not by publications.\nWhat You’ll Work On\nBuild and maintain pipelines for model evaluation, scoring, and monitoring in production environments.\n\nApply fine-tuning, optimization, and lightweight model adaptation techniques where appropriate.\n\nDevelop embeddings, classifiers, and scoring services that support natural language analysis.\n\nRun structured experiments to evaluate model performance, tradeoffs, and regressions.\n\nPartner with engineering and product teammates to translate ideas into working systems.\n\nContribute to internal tooling, dashboards, and prototypes that improve agent visibility and control.\n\nMinimum Qualifications\n5+ years of experience in software engineering, ML engineering, or applied AI roles.\n\nStrong Python skills and experience building production services or data pipelines.\n\nHands-on experience working with LLMs (APIs or open-source models) in real systems.\n\nFamiliarity with model evaluation, monitoring, and performance tradeoffs.\n\nExperience using ML frameworks such as PyTorch or similar.\n\nPreferred Qualifications\nExperience with GenAI evaluation, observability, or safety tooling.\n\nFamiliarity with embeddings, vector search, or semantic similarity systems.\n\nExposure to fine-tuning, PEFT, or cost-aware inference strategies.\n\nExperience working in early-stage or fast-moving product teams.\n\nWho Thrives Here\nResearchers who like to build, iterate, and see real impact quickly.\n\nPeople who enjoy working in-person with a small team on hard, novel problems.\n\nBuilders who combine scientific depth with strong engineering instincts.\n\nIndividuals passionate about defining how autonomous AI agents are evaluated, governed, and optimized.","description_format":"text","description_chars":2900,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["AI Evaluation & Observability","AI Governance & Compliance"],"lifecycle":[{"event":"open","at":"2026-09-12T02:36:33Z"}],"liveness":{"score":9,"band":"cold","label":"Long shot","p_open":1,"p_active":0.324,"p_room":0.28,"age_days":148,"expected_fill_days":42,"reasons":["conf:12","win:tail","crowd:"],"computed_at":"2026-10-01T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/alterion-senior-applied-ai-engineer","json_url":"https://alion.io/job/alterion-senior-applied-ai-engineer.json","meta":{"generated_at":"2026-10-01T11:05:56Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","usage":{"tier":"crawler","counted_by":"address","units_charged":1,"used_today":2490,"day_limit":5000,"remaining_today":2510,"minute_limit":60,"resets_at":"2026-10-02T00:00:00Z"}}}
